so should i just leave the females in the tank then? and how much should the changes be? Anything else i can do to heal them? (i know dropsy is fatal but i still want to prevent the others from getting it)

Dropsy can be caused by multiple things. The swelling of their body is caused by organ failure/inability to remove fluids and toxins from the body and the pineconing can appear with that and is a big factor of dropsy.

I can really only think water quality if your bettas are all getting popeye. I recommend at least one 25% WC once a week and hope that no one else gets sick, but OFL or Adastra, or Lion Mom, could give you more experienced information for what you're going though.

By the way i think that queenie and ember both had dropsy when i first bought them as they were always this fat but the guy told me they were full of eggs when i asked if they had dropsy.... so that part may not be my fault but i will still do the more frequent water changes and i will definetly be more careful when i buy my fish from now on.

I know some people who have had bettas with dropsy that didn't get pineconed, which is why I said what I did. But pineconing is very common with dropsy. Females DO get fat with eggs but you can normally tell a difference between fat with eggs and dropsy.

It would be much easier on you if you got your own water testing kit. If you're keeping multiple fish in a cycled tank, you need to be able to test your own water. This way you know if there's a spike in ammonia, or nitrates and you'll know if your water change schedule is adequate. High nitrates are just as bad for fish as ammonia and nitrite. Do you vacuum the gravel when you change the water?

I do have a gravel siphon but i don't use it. I just scoop water out and put clean water in. I don't have a test kit right now because i'm saving up for much needed dividers for my 20 gallon and the fish store tests water for free. When i can afford one though i will probably get one. I feel so guilty, I looked a rose and she has a big thing coming of off one side of her face (i think its skin because it is the same color as her pale body) and one side looks deformed and mouth has a weird new shape too. she cant even eat extremely small pellets..... i don't know if i should put her down or if i should them both down........ i love them too much and i already feel so guilty because I caused this to happen....

I think you need to start using the gravel vacuum. With just scooping the water out you won't get any of the fish waste off of the bottom of the tank and that will cause your tank to have some crazy ammonia in it.
